On the Owen Set of Transportation Solutions

This paper presents an axiomatic characterization of the Owen set of transportation games. In the characterization we use six properties including consistency (CONS2) and splitting and merging (SM) which are firstly proposed and defined for this setup in the present paper.     

现代汉语三音节词的判定问题

三音节词在现代汉语词汇中占有一定数量,识别和判定现代汉语三音节词是一项重要的基础性研究工作,具有重要意义。判定现代汉语三音节词不能以词典是否收录和是否标注词性为依据,而是要以实际使用的情况和人们的词感为依据,坚持语音、语义、语法、语用和语感综合考察,以语用和语感为主的定性标准。具体操作上可采用语音形式识别法、语素数量识别法、语素性质识别法、语法特点识别法、语义特点识别法、语用对比识别法等方法。

Likelihood Inference for Unions of Interacting Discs

Abstract. This is probably the first paper which discusses likelihood inference for a random set using a germ‐grain model, where the individual grains are unobservable, edge effects occur and other complications appear. We consider the case where the grains form a disc process modelled by a marked point process, where the germs are the centres and the marks are the associated radii of the discs. We propose to use a recent parametric class of interacting disc process models, where the minimal sufficient statistic depends on various geometric properties of the random set, and the density is specified with respect to a given marked Poisson model (i.e. a Boolean model). We show how edge effects and other complications can be handled by considering a certain conditional likelihood. Our methodology is illustrated by analysing Peter Diggle's heather data set, where we discuss the results of simulation‐based maximum likelihood inference and the effect of specifying different reference Poisson models.     

从绍兴文理学院学生五项素质追踪研究看当代大学生的身体素质

先秦汉语一种特殊的方位短语:中+名词

先秦汉语存在一种特殊的方位短语:中+名词。先前的研究成果主要从押韵和类型学角度对这种语法现象给出了解释,但所作的解释都具有局限性。先秦时期方位词中没有实在的方位义,这一时期方位词的出现不是语法上的要求,这造成了方位词中不会受到语法和语义上的制约,它与名词构成方位短语时,语序也就显得十分灵活,可以出现在名词前也可以出现在名词后。方位短语中+名词在中古汉语和近代汉语中仍然存在,现代汉语也有这种语法现象的残留。     

Improved attribute acceptance sampling plans based on maxima nomination sampling

This paper demonstrates the use of maxima nomination sampling (MNS) technique in design and evaluation of single AQL, LTPD, and EQL acceptance sampling plans for attributes. We exploit the effect of sample size and acceptance number on the performance of our proposed MNS plans using operating characteristic (OC) curve. Among other results, we show that MNS acceptance sampling plans with smaller sample size and bigger acceptance number perform better than commonly used acceptance sampling plans for attributes based on simple random sampling (SRS) technique. Indeed, MNS acceptance sampling plans result in OC curves which, compared to their SRS counterparts, are much closer to the ideal OC curve. A computer program is designed which can be used to specify the optimum MNS acceptance sampling plan and to show, visually, how the shape of the OC curve changes when parameters of the acceptance sampling plan vary. Theoretical results and numerical evaluations are given.

貂蝉“连环计”故事的文化解读

貂蝉“连环计”故事来自民间,之后被文人接受。元明时期,“连环计”故事备受欢迎,主要体现在文人与民间在创作上的有意偏好、戏曲选本对《连环计》杂剧和《连环记》传奇的浓厚兴趣和《连环记》传奇的备受赞赏三个方面。“连环计”故事具体地说,实际上是历史加计谋加美女的故事。文人与民间对由这三种因素组合而成的“连环计”故事的喜爱,体现的是重史、尚智、爱美的共同民族文化心理。     

Chan-Vese图像分割模型的快速实现算法的研究

重初始化是水平集方法耗时的一个主要原因,通过将水平集函数与符号距离函数的偏差作为能量项引入C-V模型,以此来约束水平集函数成为符号距离函数,从而去掉了重初始化步骤。在检测多目标时,采用了曲线族代替单曲线作为初始曲线。在数值算法上,利用加性可操作分裂算子(AOS)消除了对时间步长的限制,可以选择大步长,从而加速了演化过程而且绝对稳定。实验结果表明,分割速度相对于经典的C-V模型有了很大的提高,而精度损失可以忽略。
